Agricultural composition, method for the production thereof and uses in the treatment of cultures

摘要

The present invention relates to an agricultural composition and the uses thereof to protect crops against attack by plant pathogens and/or to improve the resistance of crops to infections caused by said pathogenic agents and/or to enhance the tolerance thereof to abiotic stresses, such as those caused by cold, salinity and drought. Said composition comprises an association of an at least partially depolymerized chitosan with a bivalent copper chelate. The composition has shown to be particularly suitable-for treating oidium infections. It is moreover useful against the propagation of viruses and/or particularly effective as a biostimulant to plant and fruit growth and/or able to extend the shelf life of fruit and seeds.

主权项

1. An aqueous agricultural composition comprising:
a) an at least partially depolymerized chitosan; b) a bivalent copper chelate, wherein the chelate comprises an organic acid or amino acid; and c) a water soluble C1-C15 organic acid and wherein the chelate is completely soluble in the aqueous composition in an amount effective to completely solubilize the chitosan in the aqueous composition.
